Journal Title：Precambrian Research

Precambrian Research publishes studies on all aspects of the early stages of the composition, structure and evolution of the Earth and its planetary neighbours. With a focus on process-oriented and comparative studies, it covers, but is not restricted to, subjects such as:

(1) Chemical, biological, biochemical and cosmochemical evolution; the origin of life; the evolution of the oceans and atmosphere; the early fossil record; palaeobiology;

(2) Geochronology and isotope and elemental geochemistry;

(3) Precambrian mineral deposits;

(4) Geophysical aspects of the early Earth and Precambrian terrains;

(5) Nature, formation and evolution of the Precambrian lithosphere and mantle including magmatic, depositional, metamorphic and tectonic processes.

In addition, the editors particularly welcome integrated process-oriented studies that involve a combination of the above fields and comparative studies that demonstrate the effect of Precambrian evolution on Phanerozoic earth system processes.

Regional and localised studies of Precambrian phenomena are considered appropriate only when the detail and quality allow illustration of a wider process, or when significant gaps in basic knowledge of a particular area can be filled.

Precambrian Research 发表关于地球及其行星邻居的组成、结构和演化早期阶段各个方面的研究。它侧重于面向过程和比较研究，涵盖但不限于以下主题：

(1) 化学、生物、生化和宇宙化学演化；生命的起源；海洋和大气的演变；早期化石记录；古生物学；

(2) 年代学和同位素及元素地球化学；

(3)前寒武纪矿床；

(4) 早期地球和前寒武纪地形的地球物理方面；

(5)前寒武纪岩石圈和地幔的性质、形成和演化，包括岩浆、沉积、变质和构造过程。

此外，编辑们特别欢迎以过程为导向的综合研究，这些研究涉及上述领域的组合以及证明前寒武纪演化对显生宙地球系统过程影响的比较研究。

只有当细节和质量可以说明更广泛的过程，或者可以填补特定领域基础知识的重大空白时，才认为对前寒武纪现象进行区域和本地化研究是合适的。
